Read the tag for the habitat, then buy that kind. Care for the plant you already have on How to Grow Brittlebush. [3] [4]

Acton brittlebush is the inland kind, with many slender branches from the base, silvery-green leaves, and solitary yellow heads. Tags may say Acton encelia. Buy it for inland heat, not as the woolly desert mound and not as coast sunflower.
